ABSTRACT:
The present invention provides a fluorescent X-ray qualitative analytical method of determining elements in a sample by preliminarily measuring a standard peak position corresponding to an energy position of fluorescent rays generated from each element expected in a sample. The standard peak positions are then stored. The sample is then radiated with X-rays to cause fluorescent X-rays to be generated from the elements in the sample. Spectral data is obtained from the fluorescent X-rays to determine the peak-generating positions from the spectral data and then a comparison is made with the stored standard peak positions to determine the elements contained in the sample.
